Canine oocyte diameter in relation to meiotic competence and sperm penetration

This study was conducted to determine the diameter of canine oocytes that are able to attain full meiotic competence and sperm penetration. Oocytes were collected from ovaries of bitches at various stages of the estrous cycle. Only healthy-looking cumulus-oocyte complexes were used for in vitro matu...

Description
Summary:This study was conducted to determine the diameter of canine oocytes that are able to attain full meiotic competence and sperm penetration. Oocytes were collected from ovaries of bitches at various stages of the estrous cycle. Only healthy-looking cumulus-oocyte complexes were used for in vitro maturation, and were divided into four groups based on diameter:
